, MACHINE FOR SHAPING UPPERS O ER LAS'IS.

Application filed August 8, 1924. Serial/No. 730,929.

This invention relates to machines for shaping uppers over lasts in the manufacture of boots and shoes, and is herein illustrated in its application to a machine organized to pull the upper over the last and to last the toe of the shoe. It will be recognized, however, that in many oi its novel and useful aspects the invention not limited to machines for performing both 'nlllingover and lasting operations nor to means-for lasting the toe end of the shoe. I

Among its general objects the invention has in view the provisionot a machine or-- ganizationforflperforming lasting or pulling-over and lasting operationsmoreexpeditiously and more satisfactorily than heretofore without the need for any great amount of manual labor or forsuch a high degree of care and skill on the part otthe workman as conditions have usually demanded in the lasting of shoes. The machine herein shown is designed particularly for McKay shoe workin which the upper is fastened in lasted position at the toe bylasting tacks, but it will be recognized that in various aspects the invention is not limited in utility to that kind of work. I a

Important features, of theihvention are to be recognized in a novel Organization for shaping an upper over a. last comprising means for wiping the upper about the'toe heightwise of the last and inwardly over the bottom of the last e'., tor"upwiping and overwiping? the upper) Q The machine herein shown is provided with upwiping means and Overwiping means movable as a unit heightwise ot the too to cause the upwiping means to wipe. theupper to the edge oi the insole and to position the ovm'wiping means in the proper plane {or the o\ 'orwip- .ing operatiol'i, and with power-driven mechanism for operating the upwi ping means and the over-wiping means in. "automatically determined time relation to each other. In the organization herein illustrated, including means for pulling the upper over the last, the pulling-over means prepares the upper for the toe lasting operation and cooperates with the wiping means to produce a properly lasted toe. The pulling-over means comprises grippers for pulling the upper at the toe end and at the opposite Sides of the forepart of the last, and in the machine shown the toe gripper continues to hold the upper under tension until the upwiping means has clamped the upper about the toeand has performed a considerable portion of the upwiping operation, thus guarding against loss of the pulling-over tension and insuring a tightly lasted toe. Thereafter the toe gripper is tripped automatically to rel vase the upper. i

The invention also presents important novel features in the combination of upper fastening means with other parts of the organization. The. machine herein shown has means for driving lasting tacks to hold the toe portion of the up er inlasted position, and for purposes of eKay shoe work the tacks are fullydriven and clinched. To hold the upper properly, McKay shoes usually require a comparatively large number of toe lasting tacks driven closely together, and the line of tacks should hear a predetermined relation to the edges of the wipers. The invention, in one important aspect, provides, in combination with each of the overwiping wipers, agang of tackers movable as a unit with the wiper in fixed relation thereto, the tackers being relatively adjustable to vary the tacking line. Accordingly, when different wipers are substituted for dillerent sizes or shapes of shoes, the tackers are correspondingly adjustable to meet the requirements of the difierent wiper contours. As herein illustrated, the wipers are so constructed as to determine the adjusted relation. of the tackers, lt'wi ll be evident that in. the taeker and wiper combination provided. the invention, in variousnovel aspects,

applicable to heel lasting well asto toe lasting.

fined, for the lllOSt' part, to such features and details as'ditler from the earlier constructio'ns, and those parts of the organization which are common to the earlier disclosures will be referred to only as may he necessary for an n lerstanding of the catures ofthe present lHVQIltlOIL I As in the organization ofthe machine shown in Patent No. 1,409,190, the shoe, in

the machine herein illustrated, is positioned with its toe end pointing upward in a substantially vertical direction, and the upper ofthe shoe in that position is engaged by opposite side grippers 221ml by a toe gripper These grlppers, in their construction and mode of operation, may, be and are herein shown substantially like the disclosure of a prior rMcFeely' Patent .No. 1,030,264, granted onJuioelS, 1912, the grippers being operated to grip and pull theupper yieldingly through lever mechanism controlled by cams. on a main cam shaft 6-. A

portion of scam-controlled lever 8 for opcrating the toe gripper 1 is shown in Fig. 6-, and in further conformity to a welhknown prior construct-ion frequently utilized in machines of the same general type, the lever 8 acts upon a short lever 10 fulcrnined at one end on a pin'1-2 on the frame of the machine and connected with the gripper atits other end. The upper gripping jaws 14 of the side grippers maybe constructed in any well-known manner. The toe gripper in the contruction shown is-providedw'vith a single pair ofjaws 16 which are curved in such mani'i'er as to embrace end of the toe.

The cam shaft 0, which operatesthe grippers and various other instrumentalitics, is opeii'ated'nnd controlled by mechanism substantially as shown in Patent No. 1,409,190f

treadle 28 connectedby a rode 30 to a the upper about the.

lever 32 whieh'imparts lengthwise movement to a rod 34 (Figs; 1 and 1), this rod having a wedge face for imparting movement to a slide 36 by the action of which a spring-controlled rod 38 is released. \Vhen this rod is released it acts to lift a brake shoe 40 from engagement with an inner face on the gear.

wheel 18, and through a lever 22 and a link 14 the clutch member 261s forced into engagement with the member 24, thereby starting the cam shaft 6 in operation. It vill be understood that at the end of each stage of the cycle the clutch is release: and the brake is applied automatically to bring the-cam shaft 6 to a stop, and as usual in this type of machine the parts are thus brought to a stop first at the end of the upper pulling moven'lent of the gri pers.

While in its general aspect the invention not limited as to the character of the shoe positioning means. it is important in a machine provided, as herein shown, with automatic toe lasting niechai'iism both that the toe of the shoe be positioned with substantial accuracy in properrelation to the wipers and that the shoe be held firmly against the pressure of the wipers. For the purposes in view, the machine herein shown is provided with means for positioning the forepart of the last and shoe which is of the same general character as disclosed in Letters Patent No. 1,674,059, granted on June 19, 1928 upon an application of Arthur F. Pym, comprising a. pin 46 formed and arranged to extend through a hole inthe insole and into a hole in the bottom of the forepart of the last, as illustrated in Figs. 16 and 17. As set forth in said last-mentioned Letters Patent, the hole in the last is formed in accurately prcdcter mined relationed to the edge contour of the last'bottom, and the pin has an accurately predetermined realtion to the wipers. so that the toe of the shoe is presented-in the correct position to receive the action. of the wipers. The pin 46 projects from a plate 48 which engages'the bottom of the insole and thus assists in determining the location of the plane of the toe end of the insole in relation to the wipers. T he pin 16 and the plate 4.8 are supported on'a member 50 which is a part of the usual. sole rest of machines of this general type. 1t will be evident that in addition to positioning the toe of the last accurately, the pin 46 serves further to hold the last against displacement under the pressure of the wipers. Further to as ist in supporting the shoe there is provided a heel rest which is moved upward nto engagement with the heel end of the shoe in the first stage of the cycle, as connnon heretofore in pulling over machines. 7

Atter the machine has come to a stop at the end of the first stage of the cycle with the upper held under tension by the grippers. the operator enabled to inspect the shoe ant. to make any of the -well-lmown adjustments, for example to straighten the tip or to vary the "force by which the upper is pulled by one or more of the grippers. For varying the force of the pull of the side grippers the machine herein shown is provided with power-operated mechanisms controlled by levers 5 las shown. and described in Patent No. 1,409,190. In case it should be desired to readjust the upper in the toe gripper, the machine has means of the same general character that illustrated in Patent No. 1,029,387 for opening the toe gripper iaws and for thereafter permitting them to close again. For convenience of control the construction herein shown comprises (Figs. 2 and S) a hand lever 56 pivoted on a block 58 and connected by a link 0 to a lever 62 onone end of arock shaft (3% which is mounted in a bracket 66 fastened to the gripper lever 10, this rock shaft having fast thereon a finger 68 arranged to engage a lug 70 on the usual slide 72 con- )ltCiTQtl to the gripper easing. It will be understood. that by swinging the lever 56 to the right (Fig. 8) the parts are operated to move the. slide 72 in the same direction and thereby to open the gripper jaws, and that upon release of the lever the jaws are automatically closed again. For greater ease of operation of the lever 56 there is provided .a handle 74 on the block 58 to be engaged by the fingers of the same hand with which the operator engages the lever 56. The block 58 is carried by a rod 76, supported partly by a strap 78 and partly by a bearing on the shaft 64:. It will thus be seen that the gripper opening n'iechanism moves with the lever 10 but is at all times in convenient position for the operator to manipulate it.

When the machine is started for the second time by depression of the treadle 28. shoe supporting means is moved into engagement with the top of the forepart of the shoe. This shoe supporting means and its operating mechanism are similar in many inspects to the disclosure of Patent No.

machine herein shown. there is provided a pad '80 mounted on a holder 82 which is slidingly moveablo in a bearing member 8 1; in directions heightwise of the shoe. a spring 86 being provided for pressing the holder 82 toward the shoe and for thus rendering the shoe supporting pressure of the pad yieldablc. The member S i ad 'justably secured to an arm 88 mounted to swing on a rod 90 carried by a. supporting arm 92 which is mounted at 94- on the frame for movementabout an axis at right angles to the axis of the rod 90. The arm 88 is initially inclined laterally of the shoe at For engaging the shoe. in the such an an le that the ad 80 is .ositioned at one side of the shoe and before depressing the. starting treadle for the second time the operator swings the arm-manually to Gay carry the pad into a position opposite tothe topof the forepart of the shoe. VVhenthe machine is started the arms 88 and 92 are swung as a unit about the axis 94 to force the pad yielidingly egainst the shoe. For

this purposethe arm 92 is connected by a link 96 to a cam-operated slide 98. In the machine herein shown the cam for operating the slide 98 is so sl-iaped as to impart to the arm 92 a portion only of its full movement at the beginning of the stage of the cycle under discussion, thereby applying the pad 80 to the shoe with sufiicient pressure tohold it effectively for the side wiping and tacking operations, and thereafter near the end of the. same stage of the cycle the cam imparts 'lurther movement to the arm, as more fully 11617013111150? explained.

In the second stage of the cycle, after the pad 80 has been applied to the shoe, the portions of the upper which have been. pulled by the side grippers are wiped inwardly over the bottom out the insole and are iasserve also to support wipers 104' or a wellknown type and pads 106 for clamping and holding the upper at the sides or the shoe. It will be'understoodthat the tucker arms and the side grip aers 2 are swung in-.:

wardly together and that by enggement of the tacker arms with latch members 108 on the side grippers these'grippers are caused to release the upper. 'lherea'fter the tacks r? are driven, and similarly tov the op.-.

eration of the machine shown in Patent No.

1,409,190 the side tucker arms and their wvipers and tackcrs are then withdrawn from the shoe and returned to starting position before the machine comes to a stop at the end of the second spi e of the cy le 7 In the n'i'cu'ntiine the toe gripper has maintained its h .hl upon the upper.

F or lasting the toe of the shoe there is provided a wiper carrier 110 mounted to swing heightwise of the toe on a bearing rod 112;

which is fast in a vertically movable slide 114' mounted in guidewuys in a portion oi the frame of the machine. For supporting it on the rod 112 the wiper carrier 110 18 provided with '22. pair or upwardly extending arms'llfl. It will he understood that the upwiping n'reans, hereinafter described, is carried into igegeinent with thetoe and face of the shoe by downward movement of its supporting means including the slide 114.

It is desirable that the u-pwiping, means he maintained yieldingl y in'engagement with the end face of the toe, and for this purpose there is secured to the wiper carrier'llt) an arm 118 connected at its upper end to a that the openings in the arms 116 through] which the rod 112' extends are enlarged above and below the rod, thereby permittingrelative upward or downward movement-- between the wiper carrier- 110 and the slide 114, so that when downward movement of the wiperv carrier is stoppedby the shoe the slide 114 may continue itsdownward move. ment against resistance of the spring 124, thus applying yielding pressure to the shoe through the Wiper carrier and the wipers. A threaded member 126 (Fig. 6) through which the plunger extends, cooperating with nut 128 on the upper end of the plunger, serves. to limit adjustably downward movement of the wiper carrier 110' relatively to the slide 114, audit will be seen that when the parts are in idle positionthe wiper carrier is thus supported by the, plunger 120 the rod 112 being positioned be tween the upper and lower ends ot' the open?. ings provided in the arm 116. It will be understood that there is provision for sufficient playin the connections described'to permit such short swinging movements as the wiper carrier has about the rod 112.

-Fo1' wiping the upper heightwise of the toe the wiper carrier 110 carries a. pair of wipers 130 (Figs 6,; 9 and 11;) comprising plates having edges curved toconform substantially to the contour of the toe, these edges in the construction shown, being faced or covered by a strip or band 132 01 flexible material, for examplmleather, arranged to extend continuously about the toe from one sideoi the toe to the other'sid'e. The wipers 130 are mounted in a recess in the wiper carrier 110 and are fastened; tohgear segments 134 movable in curved paths and having teeth which internicsh with the teeth of p'inions 136., Engaging these pii'iions are rack bars 138 pressed downwardly by springs 140 to maintain. the wipers 130 normally in open position. The wi 'icrs 130 are c losed about. the too by relative movement of the wiper carrier 110 and the rack bars 138, as more fully hereinafter explained. Since it is-desirable that differently shaped wipers 130 be sometimessubstituted for differently shaped toes, provision is made for readily detaching the wipers. For this purpose there are provided; pins, 142 extending through the gear segments 134.1nto. openings in the wipers, these pins having flanged heads which are sl dahle in curved slots. 144

1 carrier.

formed in members 146. The members 146 are movable in openings (Fig. 10) formed in the wiper carrier 110 to withdraw the pins 142 from the wipers 130 and thus to release the wipers, the members 146 having handles 148 for convenience inmanipulating them.

To position the toe lasting mechanism clear of the side Wiping and tacking devices when the latter are operating on the shoe, it is necessary that the Wiper carrier 110 be maintained at a considerable elevation above the end of the toe, and for convenience the machine herein shown is accordingly provided with mechanism for moving the carrier 110 downwardly to carry the wipers approximately into operative position, and

with additional mechanism for thereafter completing the downward movement of the For thus moving the wipers approximately to operative position, the slide 114: is formed with a transverse guideway in which is slidably mounted a block 150 (Fig. 6) engaged by a crank pin 152, the latter being carried by a shaft 154; mounted in bearings in an additional vertically movable slide 156. The shaft 154 is connected by beveled pinions 158 to a vertical shaft 160 mounted in upper and lower hearings in the slide 156, and keyed to the shaft 160 a spiral gear 162 engaged by a spiral gear 16st which is fast on a shaft 166 The shaft 166 is provided with a clutch 168 for connecting it to a constantly rotating spiral gear 170 driven by a cooperating gear wheel 172 on a shaft 174. The shaft 174 is connected by spiral gearing 176 to a shaft 178 which is connected in turn by beveled gearing 180 (Fig. 6) to a shaft 182 on which is a gear wheel 184 driven by a gear wheel 186 loosely mounted on a shaft 188. The gear wheel 186 is driven by an internal gear formed on the pulley 26 through pinions 190 and 192 fast on. a shaft 194. It will. thus be seen that the constantly running pul- .ley 26, through the connections described, rotates the spiral gear member 170 contin uously, and when this member is clutched to the shaft- 166 movement is imparted to the crank pin 152 to move the slide 114 downwardly.

The toe lasting mechainsm is started in action near the end of the second stage of the cycle of the main cam shaft 6 during which the upper is wiped over and tacked at the sides of the forepart at the rear of the toe, as hereinbefore explained, and for thus initiating the operation of the toe last ing means the clutch 168 is controlled by mechanism operated by the cam shaft 6 before the latter comes toa stop. It has already been explained that the cam for operating the shoe supporting arm 92 imparts to the arm a supplemental movement near the end of the second stage of the cycle thus increasing the pressure of the pad 80 on the shoe. The principal reason for thus imparting successive movements to the arm 92 is for convenience in utilizing the second movement of the arm to trip the clutch 168. For nirpose the arm 92 carries a pin 196 (Fig. 1) which engages a spring-controlled latch 198 carried by a lever 200, this lever bei connected by a link 202 to a bell-crank memocr 204: for controlling the clutch 168. This clutcl'i maybe of any suitable type, and herein shown as a wellknown form of pin cl "h which is tripped by movement of the depending arm of the bell-crank 20%. it will be understood that the pin 196 slips past the atch 198, thus immediately releasing the lever 260 and the bell-crank 20st to the action of a spring 206 which returns the bellcrank into position to release the clutch 168 at the completion of one revolution of the shaft 166. The spiral gears 1.62 and 164 are so proportioned as to impart to the shaft a half revolution for one revolution of shaft 166, thus turning the crank pin 1 to its lower limit of movement where itcmains throughout the operation of the toe means on the shoe.

ore the shaft 166 comes to a stop it acts to start in operation means for imparting fin-ther downward movement of the wiper carrier 110 and for carrying out the cycle of operations of the toe lasting mechanism on the shoe. This means includes in its or anization a cam shaft 208 having thereon a spiral. gear wheel 210 driven by a worm 212 on a shaft 214, this shaft being connected by beveled gearing 216 to the shaft 188 on which the gear wheel I86 turns as hereinbefore explained. The gear wheel 186 shaped to serve as one member of a clutch, cooperating with a clutch member 218 which is keyed. to the shaft 188 and is slidable thereon. The member 218 is pressei by a spi 220 toward thewhcel 186, but is controlled by a crank arm 222 fast on a rock 't 224: (Fig. 2.), this shaft having an arm 26 connected by a link 228 and a b ellcrank 230 to a link 2532. Thelink 232 has thereon. a member 234 engaged by an arm 236 which fast on a cam-controlled rock shaft 288 to hold the clutch member 218 normally out of engagement with the member 186 against the resistance of the spring 220 and in engagement with a brake member 2 16. Vhen the link 2532 is swung upwardly to disconnect the member 234 from the arm 236. the spring 220 is permitted to act on the clutch member 218 to release it from the brake and to set the clutch, thus starting the cam shaft 208 in operation. For thus raising the link it is connected by a link 24-2 to one arm 0; a lever 2 the other arm of which carries a roll 24.6 arranged to be engaged by a member 248 on a disk 250 operated through gearing 252, 254 by the shaft 166.

. new

It will be seen that the proportion of the gears 2'52, 254 is such that the disk 250 is turned through only a heilif revolution to one revolution of the shaft 166 end the; the member 248 acts on the lever 24 1 substan- -ielly'et the end of the revolution of the slnti t 166, immediately releasing the lever 2 14 so that the ineniber 2% is dropped downwardly again to be acted upon the member at the prepcr time to disconne t the clutch. as hereinafter explained.

time at its lower dead center end the :fore acts as e rigid connection to i'ipurt i-urther downward movement to the slide ll linitil the spring 124is ceinp wed somewhat, es already explained. For the purpose of this downward ='n1oV-en1-en't there is connected the slide 156 a twoernied link 2 connected to a peir of lever errns 25S 8 end 6) mounted to turn about a. shaft 260 end fixed to these lever arms is an arm 262 having a can-1 roll 26 1 operated by e path earn formed in one side of e ce in wheel 266 test on the shaft 208.

As 'he-reinbefore stated, the olosi'ngof the upwipi ngwipers 130 ebout'the toe is effected by relative movement of the wiper carrier 110 and the rack bars 138. For efi ecting-end controlling the closing of these wipers there are provided lever arms 268 test on e rock sheft 2'70 and forked at their front ends to embrace the rack bars 138. The shaft 270 is provided (Fig. 6) with a crank are 272 connected by a link 27% to a crank erin 276 on e' shaft 278, and connected to the arm 276 is an arm 280 healing e cam roll 28 engaged by a peripheral cam (7-11 the shaft 208. Slidingly mounted on the reel: bars 138 are men'ibers 286 pressed, downwardly by springs 288 into engagement with limit stops 290011 the bars. In that portion of the downward inovementof the wiper carrier 110 which is eli 'ected by tu'rning'of the crank pin 152 the members 286 are carried substantially into engagement with the lever erins 268 Subsequently, in time relation to the further downward movement of the wiper carrier, the arms 2681111: operated by their earn 284% to move the inein'hers 286 upwardly, thereby closing the wipers about the toe and pressing theni yieldingly the sides of the toe through compression of the springs 286.

By reference to 1'? it will be seen that the wipers 130 are closed about the toe at it short distance from the plane of, the insole.

It will be j understood that the crank nm 152 is at this After the wipers halve been thus closed, and,

with the bend 132held in firm il 'rictionul enswinging the Wiper carrier 110 about the rod 112. It will be seen that the "wiper carrier 110 is provided its opposite sides with guidewe'ys 292 in which mounted the machine and ere connec (fi"}il urn s 2-300 first on the ioch'sha'ft 260. Also fast on the s-fhel't 260 a crank urin 302 provided with e'ceni roll 804 engaged by 1a path cam formed in one side'of a carer wheel 306 on the shaft 208. Through these c-ennections the required swinging move ment is in'ipsrted to the wiper carrier for upwiping the upper ebout the toe.

Substantially the end oi the upwipiing operation 't e toe gripper is tripped 'to cause it'to release the upper. By reference to Fig. 6 it will be seen that the toe gripper is provided es heretofore with e finger 308 for tripping it, end in the upper pulling oper etion this finger is carried under the end of e lever 310 which is ply-otellymounted above the gripper. For operating the finger 308 to trip the griop'erone-erin'ot the lever 310 is engeged by the end of a lever 312 she ft 31 1 on which is mounted a lever a-rin 316 slotted at its outer-end to embrace a pin 318 carried by one of the link 'inenibers 298 hereinbetore mentioned as a part of the inc/ens for imparting to the wipers their upwiping movement, the pin 318 being mounted on e slide 319 which is adjustable to very the time when the gripper is tripped, as indicated in Fig. 1. A spring 320 serves tohold the lever 810 in position for the finger 308 to be carried under it. The lever slide here ter referred to as part of the means for determining the vertical position of the toe gripper.

After the upwiprne; oper on has been In ..'n" m oriented end while the upper is held clamped contnously, free from wrinkles, about the toe by the wipers 130 and their hand 132, the inergin'ot the entire toe portion of the upper isgethered and wiped inwardly over the inslides 294 piyota lly connected horizontal slides 296, which are mounted in the 'i'remeof Y ed hy links 998 to ill] =6 and 7), this lever being carried bye reel:

screws 330 having plane heads norm ally sunk in corresponding depressions in the wiper plates (Fig. 12), these screws being threaded through the gear segments 328 and having slots at their inner ends facing the front of the machine to be engaged by a screw driver inserted through openings provided in the gear segments 134 and the wiper carrier 110, as shown in Fig. 9. It will be understood that in detaching the wipers the screws 330 are turned enough to remove their heads from the depressions in the wiper plates, whereupon slots 331 in the wiper plates permit the latter to be readily detached.

The slide 326 is guided in the wiper carrier 110 for movement closely adjacent to the upwiping wipers 130, and the wipers 324 are positioned to operate in a plane immediately at the rear of the wipers 130, as shown in Fig. 6. The slide 326 carries gear segments 332 provided with gear teeth in en gagement with the teeth of the wiper carrying segments 328 and also provided with gear teeth engagingthe teeth of rack bars 334 which are movably mounted intheslid e 326. Springs 336 act onthese rack bars to hold the wipes 324 normally in open position. At their outer ends the rack bars 334 have offset portions provided with adjustable screws 338 the ends of which are arranged to engage plnngers 340 (Fig. 9) controlled by springs 342 mounted in the wiper carrier 110 upon downward movement of the slide 326 relatively to the wiper carrier. In this way the rack bars 334 are rendered effective yieldingly to cause the wipers 324 to close inwardly over the shoe in response to further downward movement of the slide 326. Pins 343 carried by the wipers 324 are arranged to engage shoulders 345 (Figs. 11 and 18) on the upwiping wipers 130, sothat these wipers, which are positioned as determined by the contour of the shoe, limit the overwiping movement of the wipers 324 and determine the distance from the edge of the shoe bottom at which the tacks are driven, as will bemore fully understood from a consideration of the relation, hereinafter described, between the wipers 324 and the tackers. It will also be seen that the pins 343 by their engagement with the wipers 130 act to increase the pressure of these wipers on the shoe as the overwiping operation is completed. To assist in supporting the slide 326 there are provided springs 344 seated in re cesses in the carrier 110 and engaging lugs 346 on the'slide 326.

For operating the slide 326 to advance the wipers 324 and cause them to close through the operation of the mechanism above described, there is provided a slide 347 (F 6) connected by a link 348 to a toggle 349, 350, the arm 349 being pivoted on the rod 112 and the arm 350 connected to the slide 326. The slide 347 is connected by a link 352 to a lever arm 354 which carries a roll 356 operated by a path cam formed in one side of the cam wheel 266. d

When the wipers 324 receive their advano ing and closing movements, movement imparted to the toe. gripper 4 to carry it out of the path of movement of the wipers and of the tackers which move with the wipers. The toe gripper (F 6 and 7) is sup ported on a roll 358 which is carried by vertically movable members 360 supported by springs 362 upon a. piate 364 which rests upon the upper end of the slide 322 hereinbefore referred to as carrying the gripper tripping lever 310, this slide being mounterv in guideways in the men'ibers 360. i The slide 322 is connected to a rack bar 366 engaged by the teeth of a gear segment 368 which is also provided with teeth engaging rack teeth 370 formed on the wiper advancing and closing slide 347. It will thus be seen that when the slide 347 receives its operative movement the rack bar 366 is moved downwardly to carry the toe gripper downwardly in response to the resulting downward movement of the slide 322 and the members 360. The

- toe gripper is held between the roll beneath it and a roll 371 above it, the roll 371 being mounted on the slide 322 at the axis of the lever 310, and the gripper is clamped between these rolls by the springs 362 which press upwardly against nuts 373 on rod: which are carried by the members 360. By reference to Fig. 6 it will be seen that on its upper face the toe gripper is provided with a earn 375 engaging the roll 371, and in the rearward upper pulling movement of the gripper this cam permits the springs 362 to act on the roll 358 to lift the gripper and thus to impart to it a pulling movement also lengthwise of the last. The gripper is thus moved yieldingly upward in pulling the upper and positively downward to make way for the toe lasting means. The connections between the slide 322 and the rack bar 366 include a turn buckle 377 whereby the vei tical position of the'toe gripper may be adjusted.

After the upper has been wiped inwardly over the insole by the wipers 324, the wipers are made to increase their pressure on the upper through the mechanism hereinbefore described for swinging the wiper carrier about the rod 112, the cam which operates the lever arm 302 being so shaped as to impart to the wiper carrier at this time movementheightwise of the toe in the direction to increase the wiper pressure. 'lhereafter the upper is fastened to the insole about the toe by the driving of a plurality of lasting tacks t (Fig. 19) and clinching the tacks as usual in McKay shoe work. The machine herein shown is constructed to drive twelve of these tacks, but it will be understood that the number of the tacks may be varied as ill) .may be required for different shapes and 1 way in. the slide 326 in which the gear merits 328 are mounted,

Slid ably mounted upon the cover plate 374 are tacker sup porting; plates 378, one. for each of the wiper plates, having curved projections which slide in the guideway $376. Carried by the gear segments328are screws 380 the heads of which project through ci'uwed slots 3S2 (Figs. 12 and in the plate 374 and enter holes provided in the plates 378, so that the plates 378 are moved by the gear segments328 in unison with the wipers 324. Detachably mounted on eachv off the plates 378 is a casting or holder 384 for a, gang of 'taekers, the holder being provided with pro jecting aside Walls 886 between which are mounted a number of tacker plates 388 corresponding to the greatest num-herot'tacks to be driven. Each of thesetackerplates is provided with a guideway 300 tor a tack driver 392 and has thereon a pair oi? spring controlled tack fingers 394 it ming a tack pocket for holdin'g'the tack. 'Tacks are -ied to each tack pocket through a-guideway 396 from a' fiexibletack tube Each of the wipers .324 is provided with a plurality of shoulders 400 for positioning the different taeker plates 5388 with their tack pockets in proper adjusted. relation to the holes 3724 the plates'388 havingiproiee tions 402 :for Seated in recesses in the casting" "384 are springs 404, one foneachtackerplate 388, which act normally-to'hold the tackerplatcs with their projections 402 against Ithe corresponding shoulders 400. .Extendi'og tl'irough slots 405 in the several tacker plates 888 and through'the-side walls 386'of'the holder 384 are pins 408 which assist in maintaining; the'tackerplates in assembled relation. Extending across from one side wall 386 to the other isabar 410, and under this bar are positioneda plurality of finggers 412 which are mounted on pivot studs 41.4

on'the difl erent respective i'aoker pl ates 388.

In a downturned end port-ion of the bar 410 is threaded a set screw 416 which hears on one ofthe-fingers 412 and acts to clamp. all these fingers together-and againstthe opposite downturned end oiithc bar, thereby holding the several tacker plat s 2388 securely in the relation detel-mined by the shoulders 400. It will be seen that by the provision of the pivoted fingers 412 the engaging the shoulders.-

different .tacker plates 3188 are secured without any binding or cramping .aetion the plates themselves or on the operating parts associated therewith.

Each casting 384' is fastened to its supporting plate 378 means of .a. spring springs 404 :and clamped lightly by .115 t the set screw .416. The casting 384 is ithen .moved into POSllZlQlI'QIl 1t-s supportmgi plate 378 and locked by the plunger 418. The screw 416 is then loosened, whereupon the springs 404 act to slide the tacker plates into the positions determined by shoulders 400. Thereafter theset screw-416 is tightened again. i

lVlounted in guideways 422 in the side walls386 ofthe casting 384=isa tack driver head .424 which carries the tack drivers S92 the latter being fastened in blocks 426 which are mounted inguideways 428 in the head v424. The driver head 424 is normally upheld .by springs which are seated in recesses in the walls 386' and engage lungs which project from the driver head. It .will be understood that :the ,guideways 428.211'0.

in the same plar as the tacker ;p.l.ates.388 and that these guideways facilitate the semblingand adjustmentof the tackers.

J'For impartingoperative movement-to the tack driver heads 424 there are provided plunger-s 32 3, .6 and 7) which are operated by i irings 434. .These plungcrs are controlled independently of each other by peripheral cams .436 on the. am 1 208 through bell crank lever arms 438 442 y a mounted. to swing; on a shatt 44.0,the arms 442 being connected by links 44440 the respective plungers 432. By reference to Fig. 6 it will be seen thatthe cams 436 are cut away as indicated at 4461 0 release-the arms ,438and thusperniit the springs 434 to act.

By reason of =.t-he large number of tacks required the machine is preferably provided with a pair of tack hoppers 448, only one of Which is shown (Fig. 2) and withcorrespending tackseparators 450 constructed and operated as hcretotorein machines of the the same general type. It will be understood a,

that oscillatory movements .are impartedito thetack hoppers 448. in a well-known manner by a cam on the main cam shaft 6 through connections including a :link 452 a bell-crank 454, a link 45,6 and a lever 468 connected to the tack hoppers. Leading from one of the separators 450 is a group of tack tubes 460 (Fig. 9), the lower ends of which are fast in a bracket 462 on the frame of the machine, and the tack tubes 398 leading from one of the groups of tacker plates 388 have their upper ends connected to one arm 464 of the bracket 122, hereinbefore referred to, which moves upwardly and downwardly with the wiper supporting slide 114. Similarly another group of tack tubes 460 leads from the other tack separator to the bracket 462 at the opposite side of the machine for supplying tacks to the tack tubes 308 leading to the tacker plates associated with the other wiper. From one of the separators also extend a group of three tack tubes 466 for supplying tacks through tubes 468 to one of the side tacker arms 100, and from the other separator similar tubes lead to the opposite side tacker arm. It will be understood that the tacks are supplied to the tacker plates of the wiper and tacker mechanism when the slide 114 and the arms 464 are in their uppermost position.

After the tacks have been driven the cam shaft 208, continuing its movement, returns the different parts controlled thereby to their starting positions, and the cam shaft is then brought to a stop automatically by the action of a stop cam 470 (Fig. 2) comprising a projection on a cam wheel 472 which is fast on the shaft 208. This cam is arranged to act on a roll 474 mounted on a lever 47 6 which is fast on the shaft 238 'hereinbefore described, a spring 47 8 connected to the arm 236 on this shaft acting to hold the roll against the cam. It will be understood that after the starting of the cam shaft 208 in response to the lifting of the member 234, as hereinbefore described, the cam 470 moves out of engagement with the roll 474, permitting the spring 478 to swing the arm 236 to the right (Fig. 2) until this arm connects again with the member 234. Thereafter, when the cam 470 again arrives in position to swing the lever 47 6 to the left, the arm 236 acts through the member 234 and its connections to the clutch member 218 to disconnect this clutch member from its operating member 186 and to force it into engagement with the brake member 240.

In order to complete the movement of the toe lasting mechanism to starting position it is necessary that the shaft 154 (Fig. 6) be turned through half a revolution to raise the crank pin 152 and the slide 114 to their upper limits of movement. For this purpose automatic means is provided for again tripping the clutch 168, this means comprising a cam disk 496 (Figs. 1 and mounted on one end of the cam shaft 208 and provided with a projection 498 for operating a lever 500, this lever being connected by a link 502 to the clutch controlling bell-crank 204.

It is also necessary again to start the main cam shaft 6 in order that this cam shaft and the parts controlled thereby shall be likewise returned to starting position. For this purpose the cam disk 250 which is driven by the shaft 166 has a projection 480 (Fig. 2) which engages a cam roll 482 on a lever 484 and through this lever and a link 486 operates an arm 488 (Fig. 4) which is fast on a rock shaft 490 provided with an arm 492 for engaging a pin 494 on the clutch tripping slide 36 hereinbefore mentioned.

In the operation of the machine, briefly summarized, an assembled shoe is presented in position for the pin 46 to enter the corresponding hole in the forepart of the last, or in case the machine is not provided with such a pin but with a sole rest of the more common type, the shoe is positioned with the toe end face of the last engaging the toe gripper jaws 16. It will be understood that if the pin 46 is utilized it serves to support the shoe independently of the operator, thereby rendering it easier for the operator to position the margin of the upper materials properly within the toe and side gripper jaws. After the upper has thus been inserted in the gripper jaws the machine is started by depressing the treadle 28, whereupon the toe and side grippers grip and pull the upper and thesole rest member 50 receives a short forward movement in a direction opposite to the direction of the pull of the grippers. At this time also the heel rest 52 is moved up into engagement with the heel end of the shoe.

After the machine has come to a stop with the upper held under tension, the operator is enabled to make any of the usual. adjustments, as hereinbefore described, to position the upper properly in its relation to the last. Thereafter the machine is again started l depression of the treadlc 28. In this of the cycle the shoe rest 80, which has b swung by the operator into position in front of the shoe, is operated to apply supporting pressure to the top of the forepart of the shoe, the upper at the sides of the forepart at the rear of the toe is released from the side grippers and is wiped over and fastened by the tacks t, illustrated in Fig. 16, and thereafter the side tacker arms 1.00 are swung outwardly again away from the shoe. Before the cam shaft 6 comes to a stop at the end of this stage of the cycle, the lever 200 is operated to trip the clutch 168 through which the slide 114 which carries the toe lasting mechanism moved downwardly, and through themechanism controlled by this clutch the clutch member 218 (Fig. 6) is actuated to start the cam shaft 208 in operation. Through mechanism con trolled by this cam shaft the toe lasting mechanism is moved farther downwardly and the upwiping wipers 130 are closed aboutthe toe, and thereafter the Wiper carrier 110 is swungaboutthe rod 112 tocause the'wipers 130 and their band 132 to wipe the upper to the edge of the insole. At or near the end of the upwiping-,operation the toe gripper is tripped to cause it to release the upper. Thereafter, in the continued operation of the cam shaft 208, the overwiping wipers 324 are advanced and are closed over the toe end of the last to wipe the upper inwardly over the insole. :Movingas a unit with'eachof-the wipers 324 is its associated tacking mechanism, and after the wipers have'eoinp'leted their overwipingmovement the plungers 432 am released for operating the tack driver heads AQ-ltodrive the lasting tacks. In the continued operation of the shaft 208 the parts controlled thereby are returned to their starting positions, the clutch 168 is again tripped for returning the slide 11s to its uppermost position, and the main clutch also is tripped automatically to cause-the cam shaft 6 likewise tocomplete its cycle of movements. The shoe is then removed *from the-machine, the toe being lasted as illustrated in Fig. 19.

While the invention is herein illustrated in its application to a machine designed for driving lasting tacks such as are commonly used "inMcKay s'hoeworlt, it is to be understood that in manyoi its aspects the invention isnot limited inutilizty to the use of fasteningso'f'the particular form-illicit ated, and

the term tack and similar terms are accordingly used herein for convenience of designation rather than by way of limitation. 7
